My research interests are aquatic ecology, eco-evolutionary dynamics and fish biology.

My PhD studentship will investigate the complex interplay between eco-evolutionary dynamics and the extrinsic factors that lead to stage-structured populations. Using the model system of Trinidadian Guppies (Poecilia reticulata), we will examine the top down effects of harvesting versus the bottom up effects of resource usage.

Current Projects:

Eco-evolutionary responses of fish populations to novel and traditional harvesting

Collaborating with Robert Arlinghaus and co at IGB Berlin, we empirically test theory, suggesting that harvesting intermediate sized individuals as opposed to traditional bias towards largest individuals results in more sustainable and productive fisheries (Gwinn et al, 2015).


Ecological drivers for assymetrical life histories in a vertebrate model system

Few studies of wild or captive populations, even in constant experimental conditions, find juveniles and adults of the same species to ecologically symmetrical. Instead it is most often found that ontogenetic stages differ in competitive ability for resources or vulnerability to predation – Asymmetry (de Roos & Persson, 2013). Why is this the case? It is not clear and early studies of simple models have found that evolution selects for quite the opposite. In this project we explore what different ecological scenarios lead to plastic and evolved changes in the asymmetry between juveniles and adults. We do this comparatively in field populations and in the laboratory using wild derived populations of the Trinidadian Guppy.
